I don't know for certain if Dan has a website that he uses to sell any of his photos as he doesn't list a personal website on his Facebook page. But sometimes it possible to find more pictures, if not the complete photo shoot set, on a specific model's website, Facebook page or other social media. That may be the only option possible to find the complete set of a Dan Ray photo shoot if they exist online.
It would be nice if Dan had a website to post his photo shoots on. He is a great photographer IMHO and has worked with many female bodybuilding, physique, fitness, figure and bikini competitors.
